February 2019 | Overdrive | 43 E Q U I P M E N T T he 2020 Freightliner Cascadia will be the first production model tractor in North America equipped for Level 2 automation. That means the truck, manned by a driver, can accelerate, decelerate and steer independently. Daimler Trucks North America announced updates to its flagship truck at last month's 2019 Consumer Electronics Show in Las Vegas, where it was named "Best Transportation Technology." The new truck delivers a 35 percent improvement in fuel efficiency when compared to 2007's first-generation Cascadia, DTNA said. Thanks to some of Daimler's automation tech- nology, the truck also will be safer. The tractor in part stems from groundwork laid by Daimler in 2015 when it unveiled its semi-autono- mous Level 3 Inspiration concept truck. The 2020 Cascadias will enter series production this summer. ADVANCED TECHNOLOGY. The trac- tor leans heavily on the Detroit Assurance safety system platform, standard on all Cascadia models, and the Detroit powertrain. The truck uses Detroit Assurance 5.0 Adaptive Cruise Control and Active Lane Assist features to enable automated driving at all speed ranges. Systems currently available work only above certain speeds. "Fleets with trucks equipped with forward collision mitigation systems can experience a 60 to 80 percent reduction in rear-end crashes," said Kelly Gedert, product marketing director for Freightliner and Detroit. Active Brake Assist 5.0 merges camera and radar technology. When it detects moving and stationary objects in the truck's path, it fully brakes to avoid or mitigate a collision. Active Lane Assist – the system that enables Level 2 automated driv- ing – consists of Lane Keep Assist and Lane Departure Protection. When Adaptive Cruise Control, which automatically maintains fol- lowing distance, is enabled, Lane Keep Assist supports the driver by using small steering movements to keep the truck centered in its lane. With Lane Departure Protection, if the truck drifts without the turn sig- nal engaged, the system will steer the tractor back into its lane and give the driver audible and visual warnings. An industry first is the optional Side Guard Assist. It detects objects, including pedestrians and cyclists, in the passenger-side blind spot and the full 53-foot trailer length and delivers audible and visual warnings. A new maintenance system uses feedback from the truck to determine optimized maintenance intervals. An optional 12-inch digital driver display offers vehicle diagnostics and can be paired with a 10-inch panel in the B-panel that can house third- party apps. A multimedia interface allows drivers to connect a smart- phone to the display. AERODYNAMICS AND POWERTRAIN. Aerodynamic enhancements contrib- uting to the Cascadia's fuel economy include a standard A-pillar deflector and an optimized roof fairing deflec- tor to improve airflow. New tow hook covers reduce the volume of air entering the front of the truck. The optional Aerodynamic Height Control electronically lowers suspen- sion height automatically by an inch at 55 mph to optimize airflow over and under the truck. Optional chassis skirts and side extenders reduce drag. Cascadia's new Intelligent Powertrain Management 6, an enhanced predictive cruise control, Improved aerodynamics and other features make the truck more fuel-efficient than prior models.
